This has been designed to teach the theories, principles and methods of analyzing environmental contaminants in a given media utilizing various instruments Gas Chromatography(GC) - Mass Spectrometry (MS), Electron Capture Detection (ECD), Flame Ionization Detection (FID), High PressureLiquid Chromatography (HPLC), Ultra Violet-Visible (UV-Vis) and Ion Chromatography (IC) and analytical techniques Solid Phase Extraction (SPE), Thin Layer Chromatography (TLC), Accelerated Solvent Extraction (ASE). The course will include sample preparation methods to detect environmental contaminants at known and unknown concentrations invarious media (soil, water, and air). This will include laboratory and homework assignments to assess student understanding of course material.
